Steps
1. Preheat your oven to 400°F (200°C).
2. In a bowl, mix olive oil, rosemary, thyme, salt, and pepper. Rub this mixture onto the lamb chops and set aside.
3. Boil the diced potato in salted water for about 15 minutes, or until tender. Drain and mash with butter, milk, and minced garlic. Set aside.
4. Toss the halved Brussels sprouts with olive oil, salt, and pepper. Place them on a baking sheet.
5. In a hot skillet, sear the lamb chops for 2-3 minutes on each side until browned, then transfer them to the baking sheet with the Brussels sprouts.
6. Roast the lamb and Brussels sprouts in the oven for about 10-12 minutes, or until the lamb reaches your desired doneness.
7. Plate the garlic mashed potatoes, top with the roasted Brussels sprouts, and place the lamb chops on the side. Serve warm.
